Hybrid tea rose plant named &#39;poulht002&#39;

ABSTRACT

A new garden rose plant of the hybrid tea class which has abundant, apricot flowers and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

SUMMARY OF THE INVENTION Botanical Classification

Rosa hybrida

Variety Denomination

‘POULht002’

The present invention constitutes a new and distinct variety of gardenrose plant which originated from a controlled crossing between thefemale seed parent ‘POULduce’, originally described and illustrated inU.S. Plant patent application Ser. No. 09/277,239 dated March 26, nowabandoned, and the male pollen parent, an un-named seedling. The twoparents were crossed during the summer of 1993 and the resulting seedswere planted in a controlled environment in Fredensborg, Denmark. Thenew variety is named ‘POULht002’.

The new variety may be distinguished from its seed parent, ‘POULduce’ bythe following combination of characteristics:

-   -   1. While flowers of the seed parent have a general tonality of        Yellow Group 3C-4D, flowers of ‘Poulht002’ have a general        tonality of White Group 155A with intonations of Yellow Group 5A        and Red Group 53B to 53C.    -   2. While the seed parent ‘POULduce’ has a flower petal count of        50-65 petals, ‘POULht002’ has 40 petals.

The new variety may be distinguished from its pollen parent by thefollowing combination of characteristics:

-   -   1. While the pollen parent has strong pink and orange flowers,        flowers of ‘POULht002’ are a blend of apricot and other light        pink hues.    -   2. ‘POULht002’ is more disease resistant than the pollen parent.

The objective of the hybridization of this rose variety was to create anew and distinct variety for garden use with unique qualities, such as:

-   -   1. Uniform and abundant apricot pink blended flowers;    -   2. Vigorous, growth;    -   3. Disease resistance;    -   4. Exceptional rose fragrance.

This combination of qualities is not present in previously availablecommercial cultivars of this type, known to the inventors, anddistinguish ‘POULht002’ from all other varieties of which we are aware.

As part of their rose development program, L. Pernille Olesen and MogensN. Olesen germinated the seeds from the aforementioned hybridizationduring winter of 1993 and conducted evaluations on the resultingseedlings in a controlled environment in Fredensborg, Denmark.‘POULht002’ was selected in the spring 1994 by the inventors as a singleplant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘POULht002’ by traditional budding and rootedcuttings was first done by L. Pernille and Mogens N. Olesen in theirnursery in Fredensborg, Denmark in July, 1994. This initial and othersubsequent asexual propagations conducted in controlled environmentshave demonstrated that the characteristics of ‘POULht002’ are true totype and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘POULht002’, as observed in its growthin a field nursery in Jackson County, Oregon. Observed plants are 3years of age and were grown on Rosa multiflora understock. Colorreferences are made using The Royal Horticultural Society (London,England) Colour Chart, 1995, except where common terms of color areused.

For a comparison, several physical characteristics of the most similarrose variety we are aware of, ‘Hombre’, described and illustrated inU.S. Plant patent Ser. No. 5,552 issued 10 Sep., 1985, are compared to‘POULht002’ in Chart 1.
